[FAQ] What to do if I get "failed to run custom build command for openssl-sys v ..." error?

[TheBinitGhimire]

Some users might get an error that says the following:

failed to run custom build command for `openssl-sys v ...`

Due to this error, the Cargo build or installation process for NtHiM might be stopped. But, there is a fix for this issue, and it is clearly mentioned at the Docs.rs documentation for openssl, which can be found here: https://docs.rs/openssl/0.10.34/openssl/

If you are one of the victims of this issue, then I would suggest you to use the following commands to resolve the issue for your respective platform.

macOS (Homebrew)

brew install [email protected]

macOS (MacPorts)

sudo port install openssl

macOS (pkgsrc)

sudo pkgin install openssl

Arch Linux

sudo pacman -S pkg-config openssl

Debian and Ubuntu

sudo apt-get install pkg-config libssl-dev

Fedora

sudo dnf install pkg-config openssl-devel

By performing one of these actions, the issue might be resolved in your case. If this doesn't resolve the issue, please let me know!

Adding the following line under [dependencies] in the Cargo.toml file can simply resolve the issue:

openssl = { version = "0.10", features = ["vendored"] }

But, this would make the NtHiM executable binary consume more memory due to OpenSSL being built into it. Therefore, I haven't included it inside the file.

You might be interested in adding this line into the file in case you are interested in modifying NtHiM to build something more interesting.

Hello @saikumar9121,

Would you mind letting me know about your system? Also, using what method are you trying to install NtHiM?

I just tried doing a fresh install on a clean, new Debian 10 instance on amd64 with only Rustup installed, and the installation was successful both through crates.io and manual building. So, I would love to know about the system where you were trying to install and faced this issue.

Thanks,
@TheBinitGhimire
